In a potential emergency situation, CYPRES 2 is an electronic
"automatic activation device" that can act as a third hand for
Felix, automatically initiating his reserve parachute should his
main become unusable. For Red Bull Stratos, AIRTEC developed a
special 'STRATOS CYPRES' that is capable of withstanding the
incredibly hostile environment found at 120,000 feet.

The release component is installed in Felix's reserve parachute
container. In the event he cannot open or trigger either of his two
landing parachutes by himself, this exclusively designed equipment
will initiate the opening of the reserve parachute at the assigned
time and safety altitude. The capabilities of CYPRES 2 are based on
atmospheric pressure and advanced AIRTEC technology.
